Comparing Decimals Concepts

The video tutorial explains how to compare decimal numbers by using greater than, less than, and equal to symbols. It outlines three main rules: first, compare whole numbers; second, compare decimal places starting from the tenths; and third, ignore trailing zeros as they do not affect the value. Examples are provided to illustrate each rule, helping viewers understand how to determine which decimal is larger or smaller in a given set.
